Intelligent anti-lost method based on user entering and exiting gate

[0018] Reference figure 1 , The present invention proposes an intelligent anti-loss method based on the user entering and exiting the gate, including:

[0019] Step S1, when it is determined that the target user enters the door, obtain the fingerprint of the target user when entering the door, and establish a communication connection between the mobile terminal carried by the target user and the target door, which specifically includes: acquiring according to the preset pressure sensor on the outside handle of the target door The real-time pressure of the target user is determined when the target user enters the door; the target user’s entry fingerprint is obtained according to the preset fingerprint collection device on the door handle of the target door; the mobile terminal carried by the target user is connected to the same local area network as the target door to establish the relationship between the mobile terminal and the target door Communication link between.

[0020] In the specific scheme, the real-time pressure obtained by the pressure sensor preset on the outside handle of the target gate is judged when the real-time pressure obtained by the pressure sensor is greater than the preset threshold. The preset fingerprint collection device obtains the entrance fingerprint of the target user.

[0021] When the target user operates the smart mobile terminal to connect to the same local area network as the target gate, the communication connection between the mobile terminal carried by the target user and the target gate can be established, or the user operates the smart mobile terminal to scan the QR code of the target gate Establish a communication connection between the mobile terminal carried by the target user and the target door. Further, after the target user enters the door, the target user can be reminded to establish a communication connection between the mobile terminal carried by the target user and the target door.

[0022] Step S2: After determining the preset time for the target user to go out corresponding to the entrance fingerprint, and the communication connection between the mobile terminal carried by the target user and the target gate is not disconnected, a security alarm is issued, which specifically includes: when the target user goes out When the target user’s exit fingerprint is obtained, and the target user’s exit fingerprint is compared with the entrance fingerprint, when the target user’s exit fingerprint matches the entrance fingerprint, the target user corresponding to the entrance fingerprint is determined to exit the door; The real-time pressure obtained by the preset pressure sensor on the handle determines the target user to go out; the sound and light alarm device preset on the target door sends a sound and light reminder for security alarm; or, by sending a message to the preset contact person of the target user To carry out a security alert.

[0023] In the specific solution, the real-time pressure acquired by the pressure sensor preset on the inner handle of the target door is determined. When the real-time pressure acquired by the pressure sensor is greater than the preset threshold, the user is judged to go out and pass the preset on the inner handle of the target door. The fingerprint collection device obtains the exit fingerprint of the target user, and compares the exit fingerprint of the target user with the entrance fingerprint. When the exit fingerprint of the target user matches the entrance fingerprint, the target user corresponding to the entrance fingerprint is determined to go out. At this time, it is detected When the communication connection between the mobile terminal carried by the target user and the target gate is not disconnected, it means that the target user has left the target gate, but the mobile terminal is forgotten in the target gate. At this time, the preset sound and light alarm on the target gate The device sends out sound and light reminders, or sends a message to the preset contacts of the target user for security alarms.

[0024] In this embodiment, when the target user is determined to enter the door, the target user's entry fingerprint is obtained, and the communication connection between the mobile terminal carried by the target user and the target door is established; after determining the preset time for the target user to exit the door corresponding to the entry fingerprint, And when the communication connection between the mobile terminal carried by the target user and the target door is not disconnected, a security alarm is issued. In this way, when the target user enters the door, the fingerprint of the target user is collected, and the mobile terminal carried by the target user and the target door are established After judging the preset time for the target user to go out corresponding to the fingerprint of the door, the communication connection between the mobile terminal carried by the target user and the target gate is not disconnected, indicating that the mobile terminal the target user will carry has been forgotten In the target door, at this time, a security alarm is issued through sound and light alarms or a message to the preset contacts of the target user to remind the target user to take away the mobile terminal forgotten in the target door in time to prevent the mobile terminal from being lost.

[0025] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Anyone familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution of the present invention Equivalent replacements or changes to its inventive concept should all fall within the protection scope of the present invention.
